Between July and September 2012, several archeological excavations were conducted in Sublaines (Indre-et-Loire) by the Institut National de Recherches Archéologiques Préventives (Inrap), under the curation of the State (Drac Centre).

At the point where the Beauce and Gâtinais regions meet, a team of 60 Inrap archaeologists is currently excavating the site of the future A19 motorway between Artenay and Courtenay (Loiret). Curated by the Ministry of Culture (Drac région Centre), this research is financed by Arcour, the future motorway operator. Of the 1,300 hectares of land concerned, over 90% has already been explored. Among the one hundred or so sites identified, that of Neuville-aux-Bois has yielded numerous structures. Enclosures, ditches, insubstantial buildings and granaries have been excavated.
